The comedienne and host of E!’s “Fashion Police” was rushed to Mt. Sinai Hospital on Thursday in New York, after she stopped breathing during throat surgery at her doctor’s office. The 81-year old comic was later placed in a medically-induced coma.

Rivers’ “Fashion Police” co-host Kelly Osbourne expressed her love for the ailing star by tweeting, “4 the first time in years I got down on my knees & prayed tonight! I encourage U 2 do the same 4 @Joan_Rivers my grandma! #inconsolable.”

Rivers, an unapologetic Brooklyn-born comic known for cracking bawdy jokes about celebrities and her own appearance, recently made headlines for blasting supporters of Palestinians involved in the Israel-Palestine conflict in Gaza.
